UNITED STATES PATENT OFFICE,

CAR-,VENTI LATO R.

SPECIFCATION forming part of Letters Patent No. 303,631, dated August"19, 1884. Y

Application nien March 4,1884. (No modem To '1f/ZZ whom, it mfr/ 1jconcern: Be it known that I, .T OHN M. FENNERTY, a citizen o1 the UnitedStates, residing at Memphis, in the county of Shelby and Stateoi`Tennessee, have invented a new and useful Car-Ventilator, of which thefollowing is a specification, reference being had to the ac companyingdrawings.

This invention has relation to ventilators for sleeping-cars,palaceears, par'loncars, or other ears which are provided with transomsor monitor portions in their roofs; and it consists in theV constructionand novel arrangement of parts, as will be hereinafter fully de!scribed, and particularly pointed out in the claims appended.

Figure l is a vertical longitudinal section,

taken through the monitor portion of the carbody, showing an interiorview of the ventilators an d the mech anism for opening and closingthem. Fig. 2 is an external perspective view or' the same. Fig. 3 is avertical sectional view showing one of the ventilators open; and Fig. 4is a horizontal sectional view taken on 5 a line above theventilator-guards and the mechanism i'or operating the ventilators.

The objects ol' the invention are to make provision for the properventilation of the ears, while at the same time providing for theexclusion of all dust, cnders, sparks, and the like.

Referring by letter to the accompanying` drawings, a designates aportion of the carbody, and b designates the inonitorportion in 5 theroof ofthe same, extending, as usual, nearly the entire length of theroof. The transom portions of the monitor-section b are composed of the.fixed framed panes c and the pivoted or hinged framed panes d, whichare pivoted or hingedat one end only, the hinged or pivoted end of cachframed pane d being next to the ends of the iixed framed panes cthroughout the series, which extends from one end of the monitor-sectionb throughout the transom portions on each side. The hinged framed panesd therefore incline outwardly in opposite directions when open, for apurpose hereinafter explained.

rEhe ventilator-guards f f are composed of o sector-shaped pieces y g,provided with ver.-

tical flanges g2 g2, through which thelseeuring- -pieces g screws arepassed to secure the sectorshaped g to the outside oi the monitor-frameto form the top and bottom walls of the ventilators when open. Thepieces or plates g g are connected near their outer corners by avertical strengthening rod or brace, i, which also serves as a stop tolimit the outward movenient of the ventilator-panes. A series ofguidebrackets, 7c, are provided, having each two rectangularguideLseats, Z l', for the rectangular portions of theoperatingrods mm', which are connected to the. hinged framed panes or ventilator panesd by arms n a', pivoted both to the rods and to their respectiveventilatorpanes d.

To the end of each of the rods m m is pivoted, in a bifurcation in theend of the same, the inner end of an angularly-bent arm, o, the outerend of which is bifurcated and pivoted to the upper end of a hand-lever,p, fulcrumed to the inner 'face of the framing near the ends of themonitor-section b. zontal rack, q, is provided on the framing near thelower end of the hand-lever p, and a stud on the inner face of thelatter engages'the rack to hold the lever to its adjustment, and consequently to hold the ventilators on the incline to which they may havebeen opened, or to hold them shut afterhavin g been closed. Therectangular guide-seats in the brackets are not in line, the upper seatsbeing farther from the framing than the lower ones, so that theuppcr rodprojects inward over the lower one. There the hinged arms n areconnected to the upper rod, m', pivot-pinso1 project downwardlytheiefrom and the lower rod, m, is provided with an elongated recess, o", inwhich the pivot-pins r are seated when the rods m m are at rest, and

either one or both series of ventilators are closed. The hand-1evers andconnections of both rods m m are alike, and are at the same end of thecar, one being above the other slightly7 as shown, where both rods areabove the ventilators, as in full lines in Fig. 1.

rlhe dotted lines below the ventilator are intended to represent the rodm, arranged below the ventilators, as it may be if desired, thehand-lever (also shown in dotted lines in said Fig. l) being pivoted atits upper end and connected near its middle to the bifurcated end ofsaid rod m. There would then be one rod A perforated hori- IOO Illv

above and one below the ventilators. One half of the ventilators areconnected to rod m, and open and close in one direction, and the otherhalf of the framed ventilator-panes d are connected by hinged arms tothe rod m, and open and close in the opposite direction, to ventilatethe car while moving in the other direction. The ventilators shouldalways open to the rear of the car.

By the use of the hand-levers the series to be opened may be operatedfrom one end of the monitor-section, and those to be closed from theother end of said section, with but little inconvenience to theoperator, the entire series to be opened or closed being operated atonce, so that there will be no danger of leaving some of Atheventilators open in the wrong direction, as is the ease where theventilators are operated separately, wherein some of them are left opento admit the dust and cinders. Besides, in sleeping-cars, especiallywith this arrangement, the ventilators may be changed to suit thedirection of the moving train without interfering with or annoying thepassengers, as they may be manipulated from the ends of themonitor-section the sleeping-compartment.

The ventilators may be thrown entirely open when desired, or may haveseveral intermediate adjustments between the opened and closedpositions, all of which are positive adjustments, and by which theventilation may be regulated to suit the changes in the atmosphere.

Having thus fully described my invention, what I claim as new, anddesire to secure by Letters Patent of the United States, is-

1. In a car-ventilator, the co1nbination,with

without entering aXed framed pane in the framing of the monitor-sectionof the car-body, of two hinged framed panes having their hinged endsadjoining the ends ofthe iXed pane, the sectorshaped top and bottomplates on the outside of the framing forming the top and bottom walls ofthe ventilators, and operating-rods connecting the hinged panes in twoopposed series, and levers and racks for shifting and holding the rodsand hinged panes to their adjustments, substantially as specied.

2. In a car-ventilator, a monitor-section having its transom portionscomposed of fixed panes, and two series of oppositely-operating hingedpanes, a hinged pane being arranged at each side of each fixed pane, andoperating rods and levers connected separately to each series of hingedpanes for opening and closing the same, substantially as specified. n

3. In a car-ventilator, the combination,with the hinged ventilator-panesand the sectorshaped top and bottom walls, of the brackets havingrectangular guide-seats, and the shifting-rods having their rectangularportions seated therein, the hinged arms connecting said rods to thehinged panes, and the pivotcd hand-levers connected to the ends of saidrods by pivotcd arms, and the perforated racks for regulating theiradjustments, substantially as specified. y l

In testimony that I claim the foregoing as my own I have hereto affixedmy signature in presence of two witnesses.

JOHN M. FENNERTY.
